I was talking to someone at a commercial company,
BeeHero, that currently makes hive sensors and such for commercial growers. They want to get into the hobby beekeeper market, and they're trying to collect info with a survey. If you'd like to participate in it, here you go:
They're giving away ten $100 Dadant gift cards to random people who fill it out. (They seem fairly reputable, and the only personal information the survey collects is your email address via Google forms, but I can't vouch for them otherwise.)
Out of interest, do people use sensors in their hives, and if so, is it useful? I feel like I'm the target market for this (I do a lot of web and Arduino type stuff), but I like my beehives analog and paper-based. I even stopped using an app to keep inspection data: I find looking back at the paper notes is soothing, getting me in a slower mindset to inspect.
